Cars may be classified by a number of different criteria and objectives. However, comprehensive classification is elusive, because a vehicle may fit into multiple categories, or not completely satisfy the requirements for anyone, but certain categories are for racers who like high performance vehicles. These categories are muscle cars, tuner cars, and exotic cars. Muscle cars are usually referred to as a variety of high-performance automobiles. Its any group of American-made 2-door sports coupes with powerful engines designed for high-performance driving.
A large V8 engine is fitted in a 2-door car, usually rear wheel drive, family-style ,mid-size or full-size car designed for four or more passengers. Sold at an affordable price, Muscle cars are intended mainly for street use and occasional drag racing. The beast under the hood of a muscle car gives the “American Muscle” in Muscle cars. There motors are monsters with power and torque such as the Shelby’s 5. 8-liter engine. This 650 horsepower engine is the most powerful V8 in production.
It’s also 102 pounds lighter than its 5. 4-liter predecessor. Engineers switched to an aluminum engine block, ditched the two-piece iron driveshaft in favor of a one-piece carbon-fiber unit, and replaced the heavy sleeves that guard the cylinder walls with a protective layer of atomized metal alloy. Now that’s what makes an American muscle car one of a kind. Although American muscle is fast, the Japanese are trying to keep up with high octane imported cars also known as tuner cars.
Usually referring to the act of improving the performance or appearance of a vehicle, tuner cars, for actual “tuning” in the sense of automobiles or vehicles, see engine tuning. Most vehicles leave the factory set up for an average driver’s expectations and conditions, tuning on the other hand, has become a way to personalize the characteristics of a vehicle to the owner’s preference. Cars may be altered to provide better fuel economy, produce more power, or to provide better handling.
Car tuning is also related to auto racing, although most performance cars never compete. Tuned cars are built for the pleasure of owning and driving. Exterior modifications include changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, spoilers, splitters, air vents and light weight wheels. The essence of modification of a tuner car is an attempt to extract the greatest possible performance—or the appearance of high performance—from the base motor vehicle through the addition, alteration or outright replacement of parts.
Although this largely involves modifying the engine and management systems of the vehicle to increase the power output, additional changes are often required to allow the vehicle to handle this power, including stiffened suspension, widened tires, better brakes, improved steering and transmission modifications such as the installation of a short shifter. Although largely invisible from outside the vehicle, certain modifications such as low profile tires, altered suspension, and the addition of spoilers can change the overall appearance of the car.
There engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, Mass air flow/ Volume air flow, etc. Modern engines employ the use of an ECM to provide the best balance between performance and emissions. Via the OBD communications protocol, the electronically controlled aspects of the engine can be modified in the process known as ‘mapping’.
Mapping can either be preformed by changing the software within the ECU (chip tuning via firmware modification), or by provide false data via plug-in hardware ( piggybacking). Mechanical components can also be replaced, such as turbochargers or superchargers. Last is the Exotic cars, also known as Supercars to describe an expensive high end car. It has been defined specifically as “a very expensive, fast or powerful car”. Stated in more general terms: “it must be very fast, with sporting handling to match”, “it should be sleek and eye-catching” and its price should be “one in a rarefied atmosphere of its own”.
However, the proper application of the term is subjective and disputed, especially among enthusiasts. So-called vehicles are typically out of the ordinary and are marketed by automakers to be perceived by the public as unusual. The supercar can take many forms including limited production specials from an “elite” automaker, standard looking cars made by mainstream companies that hide massive power and performance, as well as models that appeal to “hardcore enthusiasts” from “manufacturers on the fringe of the car industry”. Supercar” is also a label custom car retrofitters reserve for their showcase, one-of-a-kind project vehicles; typically these are very extensively-modified collectible muscle cars, sports cars or grand touring automobiles updated to the very latest “streetable” racing technology. There engines are very powerful motors such as the sixty degree V12 petrol engine designed by Lamborghini, and was the first internal combustion engine ever produced by the firm. The Conclusion.
